Title: The method of manufacturing the thin film magnetic head
Inventor: NAKASHIMA GEISHI
IPC: G11B5/31
Filed: 1987-03-21
Granted: 1990-10-10
Abstract: The method involves forming a protection film on a substrate with sets of bonding pads arranged in spaced apart rows coresponding respectively to rows of thin film magnetic head elements. The latter extend depthwise from an upper side of the protection film through the film to the lead terminals of the respective elements. A linear groove is grounded in the upper side of the protection film only along portions corresponding to each one of the rows of bonding pad sets so as to expose the end surfaces of the sets of bonding pads in each row, prior to cutting the layered structure to separate the resulting thin film magnetic head units from it. The upper magnetic layers of the thin film magnetic head elements are formed well below the end surfaces of the bonding pads.

Abstract: 본 발명은 저압 화학 증착 시스템의 반응로를 구성하는 석영튜브(Quartz Tube)에 관한 것으로, 석영튜브의 조성물인 SiO 2 에 함유된 여러 불순물중 휨(SAG)현상에 영향을 끼치는 수산기(OH - )의 농도를 10PPM 이하로 줄임으로써 석영튜브의 휨강도를 증가시켜 고온(1000∼1200℃), 장시간(8시간이상) 공정조건 하에서도 석영튜브의 휨 변형이 거의 발생하지 않도록 한 것이다. 
     이와같은 본 발명에 의하면, SIC 라이너 튜브의 파손위험을 제거할 수 있고, 튜브내 오염을 방지할 수 있으며, 라이프 타임을 46배 이상 연장 시킬 수 있는 등의 효과가 있다.

Title: Mos transistor and its making method
Inventor: SEO WON-CHOL
IPC: H01L21/336
Filed: 1992-03-14
Granted: 1996-02-02
Abstract: The MOS transistor is mfd. by (a) forming a gate oxide film on the semiconductor substrate, (b) forming a nitride film on the gate oxide film, and removing the nitride film except for an electric charge capturing portion, (c) forming polysilicon on the whole surface, and removing the polysilicon except for a gate electrode forming portion, and (d) forming a first and a second diffusion regions on the substrate over both sides of the gate electrode. The MOS transistor reduces a channel length modulation, a gate overlapping capacitance and a hot carrier injection.
Patent KR-100313469-B1 (KR)

Granted: 2001-12-28
Abstract: A channel region containing a delta-shaped doped layer (5) of a first conductivity type is produced on a doped substrate (1) of the first conductivity type by selective epitaxy. Source region (13) and drain region (14) are formed, in particular, by outdiffusion from a doped glass layer (12).

Title: Process for making kimchi
Inventor: BAEK UN-HWA
IPC: A23L19/20
Filed: 1992-04-29
Granted: 1994-11-11
Abstract: The Kimchi preparation method with bifidus consists of packaging Kimchi into pouches under 100-250 mmHg vacuum, after fermenting Kimchi with one of Bifidobacterium bifidum, B. longum or B. infantis in the amount of 0.01-0.2 wt.% till acidity value 0.4-0.6 wt.%. This process helps bifidus not expose oxygen gas.

Abstract: 본 발명은 광 기록재생장치에 관한 것으로, 최적의 레이저 파워를 결정하기 위한 회로 및 방법을 제공함을 목적으로 한다. 이를 위해 본 발명에서는 기준 레이저 파워를 리드하여 서로 다른 레벨의 테스트 레이저 파워를 계산하고, 계산된 테스트 레이저 파워 각각을 식별하기 위한 ID데이터와 EFM 테스트 패턴을 해당 테스트 레이저 파워로 특정 파티션에 ATIP 프레임 단위로 기록한다. 이후 상기 파티션 재생시에 디지털데이터로 변환된 재생 RF신호의 직류성분이 비대칭허용범위내의 값을 가질때 그와 대응되어 입력되는 ID데이터가 지시하는 레이저 파워를 최적의 레이저 파워로 결정하고, 이후 결정된 레이저 파워로 데이터를 기록한다.
